Awkward - 10.5 - window size error after connecting external monitor

Cubase
1

After having connected (and disconnected) my external monitor through HDMI Cubase’s main window stays the size it was on the external moitor (smaller) and it’s not possible to restore it to max due to missing window buttons

Mac, 10.5, High Sierra

hmmm - it’s back to normal. Beforehand it did a scan of new vst3 plugins
